Sales of winter-related merchandise plunged 21.8 percent for the three months ended Jan. 1, 2012, but this was partially offset by a 6.6 percent sales increase in non-winter categories, the company reported.

“We are working diligently to minimize the negative effects of the weather while capitalizing on the merchandise categories that respond well to warm and dry conditions,” said Craig Levra, Sport Chalet chairman and CEO.

Net sales ticked up 1.5 percent to $97.2 million, but the company’s quarterly loss expanded to $1 million from $900,000 in the comparable period a year earlier.

Online sales were a bright spot during the quarter, growing 14.5 percent on a 30.9 percent jump in web sales for non-winter categories.
